WINDOW-,SCREQEN.

SPECIFICATION forming part of Letters Patent No. 693,993, dated February 25, 1902.

Application filed July 23, 1901.

To all whom it may concern:

Be it known that I, SIMON WREATON BEN- SON, a citizen of the United States, residing at 1423 Chumpa street, Denver, in the county of Arapahoe and State of Colorado, have invented a new and useful Window-Screen, of which the following is a specification.

This invention relates to a window-screen; and the object of the same is to provide a screen which is adapted for application to the outer portion of a window-frame to permit the lower sash to be raised and lowered without removing the screen and also allow shutters or blinds to be closed without requiring a removal of the same, the improved device having particular features of construction for adjusting it to fit any size Windowframe and to facilitate its manufacture and to render it strong anddurable.

The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a front elevation of a screen embodying the features of theinvention. Fig. 2 is alongitudinal vertical section through the lower portion of the same. Fig. 3 is a transverse vertical section on the line 3 3, Fig. 2. Fig. 4 is a front elevation of the lower portion of a modified form of the screen. Fig. 5 is a transverse vertical section on the line 5 5, Fig. 4. Fig. 6 is a front elevation of the upper portion of the screen embodying the invention and showing a topclosing attachment'for application to either one or both of the other forms shown. Fig. 7 is a transverse vertical section on the line 7 7, Fig. 6.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral 1 in all the forms shown desi gnates side rails, and 2 and 3 upper and lower rails, respectively. These rails are prefer' ably formed of doubled strips of galvanized sheet-iron, which are bent to produce a box. contourin cross-section and havihg the inner contiguous edges 4corrugated or crimped to firmly bite the wire-gauze fabric 5 held thereby. The ends of the upper and lower rails are inserted in the upper and lower ends of the side rails, and the ends of all of the Serial No. 69,439. (No model.)

rails are formed with longitudinal slots 6), so that when the said ends are joined, as set forth, the slots of the side rails will be disposed at right angles to those of the upper.

and lower rails, whereby central apertures for clamping-bolts 7 are provided, and the rails are all equally expansible and contractible to regulate the dimensions of the screen as an entirety. At regular intervals rivets or fastening devices 8 are inserted through the rails in a transverse direction to bind the inner edges 4 closely against the gauze fabric 5.

As before indicated, it is proposed to arrange the screen so that the lower sash may be raised aud lowered, that the upper sash may be likewise operated to permit the screen itself to be raised and lowered, and allow shutters to be opened and closed without removing the screen from its applied position. There are numerous ways to dispose the screen for these operations, as well understood in the art; but it will be obvious that it will have to be applied in the outer portion of the frame of the window, though at other times it could be practically disposed under the sash without-permitting theoperations of said sash, asset forth. It is preferred to arrange the screen in the outer portion of the windowframe, and to accommodate the inward projec-v upwardlyprojecting securingflanges 10,

which fit tightlyin the box-like rail 3, as clearly shown in Fig. 3 of the drawings. Theflanges 10 connect with a central arch plate 12 to form the recess 8, heretofore referred to, the said plate being extended inwardlyto provide a finger-grip 13 for raising the screen, and extending inwardly and downwardly from the arch-plate is a shield 14, which closes the inner portion of the recess 8. .This construction or attachment serves to exclude flies that might enter through the recess 8, which must the tight fit of the flanges 10 against the innor faces of the frame 3 tends to hold the excluder in place, and when the screen is lowered into proper operative position the weight thereof serves to further hold the excluder in adjusted position. To remove the excluder 9 from the screen-frame, the screen is raised and the excluder drawn vertically down until the flanges 10 are disengaged from the frame 3.

The excluder shown by Figs. 4 and 5 is somewhat different from that just explained, and consists of an elongated metallic strip 17, which is terminally held by the joints of the lower rail and the side rails,- and at the central upper edge portion said strip is formed with a hook 18, which is caught between the upper edges of the lower rail. The lower edge of the strip is flush with the lower edge of the rail to which it is applied and has a central inwardly-extending convex shield 19 to cover the recess 8.

The improved screen-frame set forth can be made to fit regular or irregular windowframes, and the same principle will be employed in making frames for screen-doors, gates, or other similar devices, and the size of the mesh of the wire fabric will be proportionate to the use to which the frame is put, and what is known as chicken-Wire or other coarse-mesh fabric can be employed.

In Figs. 6 and 7 a very useful closing attachment for the upper rail of the screenframe is shown adapted for use when an open space exists between the rail of the adjacent sash and the top rail of the screen and caused by an irregularity in the window-frame or warpage and also adapted to cover an excessive space in deep window-frames, where it may be necessary to set the screen at a distance outward from the sash. This closing attachment consists of a straight strip 20, which is secured to the outer side of the upper rail of the screen and has an upper resilient roll 21 extending closely over and inwardly beyond the upper edge of the upper rail. This roll may be drawn out to cover any size space or may be reduced from a primary dimension to close a very small crevice, and thus said attachment is adjustable to fit any opening.

The improved screen-frame or door or gate frame, as the case may be, is strong and durable and being composed of a comparatively few number of parts can be manufactured with facility and cheapness. All the parts are formed of metal and will not become injured by exposure to the weather, and it will also be seen that after the wire-gauze or other fabric is secured in the several rails the latter can be adjusted to take up any slack that may exist in the gauze or fabric. The closing attachment disclosed by Figs. 6 and 7 also lengthens the screen, and in some applications the sash-rail may be disposed vertically thereover.

The frame may be made of any suitable metal other than galvanized iron, and a screen-cloth or other film may be used with the wire-gauze at times for certain purposes.

Having thus described the invention, what is claimed as new is l. A frame comprising doubled metal rails having inner clamping edges crimped transversely from end to end, and a wire fabric held by said edges.

2. A frame comprising doubled metal rails having adj ustably-interlocked ends which are fitted into each other and also having clamping edges crimped transversely from end to end, the ends of the upper and lower rails having slots therein at right angles to slots in the adjacent ends of the side rails to receive clamping-bolts and permit adjustment of the rails, and a fabric held by said crimped clamping edges.

3. A window-screen having an arcuate recess at the center of the lower rail thereof to fit over the fastening device of shutters, and a detachable excluder applied to said rail to close the inner portion of said recess.

4. A window-screen having a recess at the center of the lower rail and provided with an inner freely-detachable closure, whereby the projecting portions of shutter-fastenings may extend into the said rail.

5. A window-screen having a recess at the center of the lower rail, and an inner freelydetachable convex shield therefor having an inner closed side.

6. A win dow-screen having a slot in the center of the lower rail, and a freely-detachable attachment mounted in said slot and comprising an arcuate plate with an upper inwardly-extending finger-grip and an inner downwardly-extending shield.

7. A window-screen havinga slotin the center of the lower rail, and a freely-detachable attachment mounted in said slot and comprising a pair of flanges, and an arcuate'plate with an inwardly-extending finger-grip and an inner downwardly-extending shield.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

SIMON WREATON BENSON.
